Re: Transmit an array to a function

["Jean-Christophe Berthon" <jean-christophe berthon cgey com>]

maybe if you just pass the address of the "table" like this:
gtk_signal_connect (GTK_OBJECT(button),"clicked",GTK_SIGNAL_FUNC(function),
&widget);

then in the callback function you should be able to access your table like
this :
(taking into account that the data pass to the function is of this form :
gpointer vpData)
printf("%s\n", (*vpData)[3]);
try it maybe it work :-)
